Avon’s short-lived 10 Story Fantasy from Spring 1951. The magazine lasted only 1 issue and was edited by Donald A. Wolheim who would soon go on to be an editor at Ace books. Other than the fur-lined bikini on this cover by James Bama, this magazine is most famous for containing the first printing of Arthur C. Clarke’s “Sentinel of Eternity”–usually reprinted as “The Sentinel” and the basis for 2001: A Space Odyssey.
